ROLLER SIDE BEARING EEECIFICATION forming part of Letters Patent No.734,990, dated July 28, 1903.

Application filed May 8, 1903. Serial No. 15 6,202. (No'modeL) T0 aZZwhom it may concern:

Beit known that I, ANDREW G. STEINBREN: NER, acitizen of the UnitedStates, residing at the city of St.Louis, State of Missouri, haveinvented a certain new and useful Improvement in Roller Side Bearings,of which the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a top plan view of myimproved roller-bearing with the cap-plate thereof removed, and Fig. 2is a side elevational view of the completed roller-bearing.

This invention relates to new and useful improvements in roller-bearingsadapted to be used as side bearings between the truckbolster andbody-bolster of railway-cars; and it consists in certain improvements inthe detail construction and operation thereof, all

as hereinafter more fully described, and specifically pointed out in theclaims.

This invention relates to that type of side bearing shown in anapplication filed May 8, 1903, Serial No. 156,201, in which is shown butnot claimed some of the features of the side bearing herewithillustrated.

In the annexed drawings, A indicates a truck-bolster; B, a body-bolster;1, a supporting member bolted or otherwise secured to the truck-bolster;2, a bearing-plate supported by said supporting member; 3, a 1011-gitudinally-extended guard integral with the supporting member 1, and 4is a trunnion integral with the supporting member 1, extendingtransversely therefrom beyond the guard 8, upon which trunnion iscarried the gear or segment 5, which is secured in position upon saidtrunnion by means of the cotter 6 or equivalent securing means. The gearor segment 5 is provided with teeth '7, which mesh with a rack S, whichrack is integral with and projects laterally from the cap-plate f), withwhich is connected the bearing-plate 2, adapted to rest upon rollers 10in the carriage 11. Projecting inwardly from the gear 5 is a lug uponwhich is pivotally supported the link 12, which is in turn connected tothe lug 13, projecting laterally from the carriage l1. Owing'to thestrains both vertical and lateral to which a roller-bearing of thisclass is subjected it is essential that positivelyconnected means beprovided whereby the carriage, with its friction-reducing rollers orequivalent means, shall be restored positively to operatiye position asspeedily as possible at all times. Hence the importanceof the rack 8meshing with the gear 7 and the connection of the link 12 with the gearand to the carriage, said means effecting suchrestoration of parts as toadapt the device'to operative use at all times.

In practice it has been found that devices heretofore used to accomplishthis purpose were defective for various reasons, and to protect theseparts in the present invention the guard 3 is provided, whicheffectually prevents lateral shifting of the carriage 11 against thelink 12 or gear 5, which might have a tendency to destroy theeffectiveness of said parts or throw them out of operative connection.

In the present side bearing the truck-bolster and body-bolsters areconnected,respectively, with the supporting member 1 and bolsterplate 15by bolts, and, in addition thereto, flanges 16 are provided onthemeinbers 1 and 15, whichflan ges extend vertically a sufficientdistance to partially embrace the said bolsters, thereby removing thestrain from the bolts 17, used to connect said partstogether.

I am aware that minor changes in the construction, arrangement,'andcombination of the several parts .of my device can-be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-'- 1. In a roller-bearing, a base-plate, aguard thereon extending longitudinally thereof, a gear supportedlaterally beyond said guard, a roller-frame movable over saidbase-plate, a cap-plate movable over said roller-frame, and means onsaid cap-plate and on said rollerframe whereby they are connectedwithsaid gear substantially as described.

2. In aroller-bearing, a base-plate, a guard thereon integral therewithand extending longitudinally thereof, a gear supported laterally beyondsaid guard, a roller-frame movable over said base-plate, a cap-platemovable over said roller-frame, and means on said cap plate and on saidroller-frame whereby they are connected with said gear; substantially asdescribed.

3. In a side bearing, a base-plate, a capplate, a carriage movablebetween said plates, a rack on one of said plates, a segment inengagement with said rack, and a guard extending longitudinally betweenone of said plates and said segment; substantially as described.

4:. In a side bearing, a base-plate, a capplate,a carriage movablelongitudinally thereof between said plates, a guard projectinglongitudinally of one of said plates, a segment rockably supportedbeyond said guard, a rack on one of said plates in engagement therewith,and a link connecting said carriage with said segment; substantially asdescribed.

5. In a side bearing, a member-carried by the truck-bolster, a carriagemounted on said member, a toothed, rockable member connected with saidmember, a cap-plate with a downwardly-extending rack thereon engagingsaid rockable member, and a link connecting the carriage with saidrockable member; substantially as described.

6. In a side bearing, a support adapted to be carried on thetruck-bolster, a laterally-extending part integral therewith, a gearrockable on said part, a carriage connected with said gear, and acap-plate in en gagementwith said gear; substantially as described.

7. In a side bearing, a support adapted to be carried on atruck-bolster, arockable gear supported thereby,a carriage on saidsupport, a link connecting said carriage with said gear, and a cap-plateabove said carriage with a downwardly-extending rack engaging said gear;substantially as described.

8. In a side bearing, a support adapted to be carried on atruck-bolster, a rockable gear supported thereby, a carriage connectedpositively with said gear, a cap-plate slidably mounted on saidcarriage, and a rack extending vertically from said cap-plate inconstant mesh with said gear; substantially as described.

9. In a side bearing, a base-plate, a roller- ,frame, rollers therein, acap-plate, a rack on one of said plates, a segment on the other of saidplates in mesh with said rack, and a link connecting said segment withsaid rollerframe; substantially as described.

10. In a side bearing, a base-plate, a rollerframe slidably interlockedtherewith, rollers therein, a cap-plate, a rack on one of said plates, asegment on the other of said plates in mesh with said rack, and a linkconnecting said segment with said roller-frame; substantially asdescribed.

11. In a side bearing, a base-plate, a rollerframe, rollers therein, acap-plate movably connected with said roller-frame, a rack on one ofsaid plates, a segment on the other of said plates in mesh with saidrack, and a link connecting said segment with said rollerframe;substantially as described. 12. In a side bearing, a base-plate, arollerframe slidably interlocked therewith, rollers therein, a cap-platemovably connected with said roller-frame, a rack on one of said plates,a segment on the other of said plates in mesh with said rack, and a linkconnecting said segment with said roller-frame; substantially asdescribed.

13. In a side bearing, a base-plate, a rollerframe, rollers therein, acap-plate, a rack on one of said plates, a segment pivotally supportedlaterally of and on the other of said plates in mesh with said rack, anda link connecting said segment with said roller-frame; substantially asdescribed.

14. In a side bearing,a base-plate,a bearingsurface thereon, aroller-frame movable over and interlocked with means projectinglaterally above a portion of said base-plate, a capplate, a rackthereon,a segment pivotally con nected with said base-plate inengagement with said rack, and a link connecting the roller-frame withsaid segment; substantially as described.

15. In a side bearing, a base-plate, a capplate, friction-reducingmeans, a movable frame guiding said friction-reducing means, an integralextension on one of said plates, a rack on the other thereof, a gear onsaid extension in engagement with said rack, and a link connecting saidgear with said movable frame; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence oftwo witnesses, this 5th day of May, 1903.
